How is IP rating measured

IP rating, also known as Ingress Protection rating, is a standard measure used to determine the level of protection offered by an electrical device against the intrusion of foreign objects (such as dust and water). It is essential in various industries, including consumer electronics, automotive, and industrial manufacturing.

The IP Rating System

The IP rating system consists of two digits that represent different aspects of protection. The first digit indicates the level of protection against solid objects, while the second digit represents protection against liquids. Let's take a closer look at each digit:

First Digit: Protection Against Solid Objects

The first digit in the IP rating indicates the degree of protection against solid objects, such as dust, dirt, or accidental contact with body parts (e.g., fingers). Here are the levels of protection represented by the first digit:

0: No protection against contact and ingress of solid objects.

1: Protection against objects larger than 50 mm in diameter.

2: Protection against objects larger than 12.5 mm in diameter.

3: Protection against objects larger than 2.5 mm in diameter.

4: Protection against objects larger than 1 mm in diameter.

5: Limited protection against dust ingress (cannot completely prevent it).

6: Complete protection against dust ingress.

Second Digit: Protection Against Liquids

The second digit in the IP rating represents the degree of protection against the ingress of liquids, such as water or other fluids. Here are the levels of protection indicated by the second digit:

0: No protection against water or any liquid.

1: Protection against vertically falling drops of water.

2: Protection against water dripping at an angle of up to 15 degrees.

3: Protection against spraying water (up to 60 degrees from vertical position).

4: Protection against splashing water from any direction.

5: Protection against low-pressure jets of water from any direction.

6: Protection against powerful jets of water or heavy seas.

7: Protection against the temporary immersion in water (up to 1 meter for 30 minutes).

8: Protection against continuous immersion in water under conditions specified by the manufacturer.

In Conclusion

The IP rating system provides a standardized way to determine the level of protection offered by electrical devices against solids and liquids. Understanding the IP rating of a product is crucial for selecting the right equipment for different environments and applications. Whether it's a smartphone, a waterproof camera, or an industrial machine, knowing its IP rating ensures that it can withstand the environmental conditions it will encounter.
